Insane Hubless Motorcycle With Airplane Engine

July 11, 2018


This is a video of the Tarso Marque Concepts (TMC) Dumont, a motorcycle with hubless wheels that's powered by an airplane engine. It's presumably the lovechild of a TRON lightcycle and a Cessna. Regardless, I feel like it should really have a seatback, because if you lean too far backwards that tire is gonna give you a very unwelcome body massage. That said, I would totally ride this thing to Bike Week and hang out with the rest of my rough and tough motorcycle gang. Well, what do you dudes say, is it time for some *lifting shirt* body shots?! No? That's cool. *to bartender* I'll just have a white wine spritzer.

Keep going for a video of the the thing in action, as well as a timelapse of it being constructed while I speculate if this thing is capable of turning at all.

Thanks to Jeffrey S, who we should all have flying motorcycles already. What's taking so long?

    Now let's see it turn a corner!

  • Meh

    I didn't see any speedbumps in the video. What a coincedence.

    If you can't put knobbies on and go through dirt, it's not a motorcycle: it's a two-wheeled streetcar toy.

    This thing Looks awesome, but I agree: maybe stuff like this should be left to movies or Comics. Flying cars, however...

  • How this guy manages to keep one inch from the wheel without touching it and ripping his pants completely off is a miracle. Dangerous AF

  • GeneralDisorder

    I remember one of those biker build-off tv shows (perhaps called biker build-off) where one guy build a hubless motorcycle and when he was assembling the rear wheel he mentioned th wheel was actually a $14,000 bearing.

    Imagine owning something that has a $14,000 wheel bearing that needs replaced every few thousand miles. I suspect you wouldn't ride it much.

    Ok, I watched the build video and I see some rear airbag, but no type of front suspension or steering mechanism close ups.

    Now I have even more questions.

  • Jeremiah Mckenna

    I'll give them a lot of engineering credit. But like many on here say, it has a few issues. The noise is ridiculously loud, even at lower RPMs, and the lack of visual proof it can actually make a turn says a lot.
    But since those engines are designed to run at high/higher RPM for a sustained amount of time, these guys could be on to something with that sort of powertrain. And since I didnt watch the other video, I'm wondering what sort of transmission and final drive set up they have.

    I have always liked the hubless wheel and wish it were a little more accessible.

    Does this have some hydraulics for ride height and maybe steering?

  • Nathan Otis

    A seat back? You miss the point. Stupid things should be dangerous.

  • Andyman7714

    Just needed some dogs jumping through those wheels.

  • Jeremiah Mckenna

    And you have the next million dollar winner on America's Got Talent...

  • Doog

    Are we just gonna ignore that red light at 0:28?

  • Don't lean back : )

  • Doog

    Yeah right. Got an annoying back itch while riding? Just lean back and boom your back will never itch again!

  • TheQiwiMan

    Bet the turn radius on that thing is just awful. (which is probably why there is no footage of it trying to make any significant turns)

    And he probably has to tell himself "DON'T SCOOT BACK DON'T SCOOT BACK DON'T SCOOT BACK DON'T-" the entire time.

  • whacko

    Looks cool, but it looks unsafe to ride. Plus it makes a ton of noise driving at ~30mph and doesn't look like it could actually go much faster with those thin wheels, lack of ground clearance or real suspension.

  • Jeremiah Mckenna

    Safety is in the hands of the berider...

  • whacko

    Safety should be built into the machine as much as possible. I agree with GW that the lack of a seat back is dangerous here. IF the bike gets up to any significant speed a loose article of clothing could easily be pulled under the back wheel which would pull the rider back as well. If the rider leans back a little they risk getting tire rash.

    This is just a bad design all around. Stuff like this should be left to cartoons and comics.

    And I was thinking the front wheel attachment point it is looking extremely stressed. Once it goes, the gouge it leaves in the road will be epic.
